ALACRITTY-ESCAPES(7)

💖 Alacritty Escape Sequence Support 💖

okay bestie so welcome to ALACRITTY-ESCAPES(7), the miscellaneous information manual page that's literally just a big gorgeous list of every single escape sequence Alacritty currently supports. that's it. that's the whole vibe. no cap. ✨

---

🎀 Legend 🎀

the statuses you're gonna see are PARTIAL, IMPLEMENTED and REJECTED. here's the tea on what they mean:

• PARTIAL — bestie this one still has work left to be done on it, the glow-up is not finished.
• IMPLEMENTED — and like, when something is only partially implemented but still wears the IMPLEMENTED label? that means all the other features got rejected 💀. they said no to the rest. periodt.
• REJECTED — yeah. not happening.

also important bestie 🫶 all whitespace inside escape sequences is purely for formatting purposes, nothing more, don't read into it. all the spaces that actually matter are denoted as SP. and the escape parameters? omitted, for brevity, because we are keeping this cute and tight. 💅

⭐ ESC codes - ESC ⭐

here's the whole roster of ESC sequences and how they're doing. slay:

• ESC ( — Implemented — only charsets B and 0 are supported.
• ESC ) — Implemented — only charsets B and 0 are supported.
• ESC * — Implemented — only charsets B and 0 are supported.
• ESC + — Implemented — only charsets B and 0 are supported.
• ESC = — Implemented — no notes, just vibes.
• ESC > — Implemented — no notes, just vibes.
• ESC 7 — Implemented — no notes, just vibes.
• ESC 8 — Implemented — no notes, just vibes.
• ESC # 8 — Implemented — no notes, just vibes.
• ESC D — Implemented — no notes, just vibes.
• ESC E — Implemented — no notes, just vibes.
• ESC H — Implemented — no notes, just vibes.
• ESC M — Implemented — no notes, just vibes.
• ESC Z — Implemented — no notes, just vibes.

and yeah, every single one of those is Implemented bestie, we ate 🔥. the ESC ( ESC ) ESC * and ESC + girlies are the only ones with a lil asterisk on them (charsets B and 0 only, iykyk), everyone else is out here thriving with zero caveats. 🦋

more parts coming, don't go anywhere 👑

🎀 CSI (Control Sequence Introducer) — ESC [ 🎀

okay bestie, this is THE one. CSI stands for Control Sequence Introducer, and you write it as ESC [. it's literally the main character of terminal escape codes — cursor moves, colors, mouse tracking, all of it lives here 💅

here's every single CSI sequence Alacritty has an opinion about, plus the exact status and any notes, no skips, no "etc." 🙅‍♀️

okay so like. notice how CSI m and CSI t show up twice? that's not a typo bestie, that's real — one set of parameters gets through, the other set gets sent to voicemail 🙈 the way that matters is which parameters you actually pass, iykyk.

anyway, we're not done, keep scrolling, there's more 🌈
